The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record. Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. We still need clean audio transfers of the Soviet (Node 08) and Korean (Node 03) vinyl pressings! -- Dong-hyun Vasiliev SupraFAXModem 28.8 @ ISDN 64k bps "When every node is whole, the channel opens."
